Die Bedeutung neurobiologischer Faktoren bei der Aggressionsgenese I

Zusammenfassung

Die neurobiologischen Grundlagen der Aggressionsgenese sind noch weitgehend ungeklärt. Einer Vielzahl neurochemischer Faktoren, neuroanatomischer Strukturen und neurofunktioneller Veränderungen wird eine Bedeutung bei der Genese aggressiver Handlungen zugeschrieben. Manche der vorliegenden Ergebnisse sind noch widersprüchlich, andere Befunde wurden dagegen wiederholt bestätigt. Im Folgenden wird eine Übersicht über bislang vorliegende neurochemische Befunde und genetische Einflussfaktoren der Genese auto- und fremdaggressiver Verhaltensweisen gegeben. Wenn dabei im Wesentlichen neurobiologische Faktoren der Aggressionsgenese dargestellt werden, so im Bewusstsein, dass Gewalt multifaktoriell bedingt ist und die neurobiologischen Aspekte lediglich einen Teil des umfassenden Bedingungsgefüges der Aggressionsgenese erklären können.

Summary

The neurobiology of violence and aggression is poorly understood. A lot of neurochemical, neuroanatomical and neurofunctional factors have been described to be involved in the genesis of violence. Most of the results are heterogeneous, others have been replicated. The following article gives an overview on recent neurobiological findings on violence and aggression. In particular, neurochemical findings and genetical influences on aggressive behaviour are outlined. In the following chapter, a neurobiological approach on violence is given knowing very well that the conditions of violence are multifactorial and that neurobiology is just one part of the influencing factors of aggression.
